In a virtual machine system, an arrangement of virtual machines, which has fault tolerance, is performed. A virtual machine managing apparatus (100) includes a similar group generating unit (102) and an arrangement restriction generating unit (105). The similar group generating unit (102) generates a group of virtual machines (201) having a similarity relationship which indicates that performance values of virtual machines at each timing are approximately the same, out of plural virtual machines. The arrangement restriction generating unit (105) outputs the group of virtual machines (201) having the similarity relationship as a distributed-arrangement restriction indicating a group of virtual machines (201) to be arranged on different processing apparatuses (200) among plural processing apparatuses (200) carrying out processes of the virtual machines (201). |
